Do not restart the inverter until the source of the problem has been identified and corrected. • To avoid battery drain, always disconnect the inverter when not in use. • Do not expose the inverter to moisture. • Avoid placing the inverter near sources of heat or in direct sunlight. • When in use, make certain that the inverter is properly ventilated. • Do not use the inverter near flammable materials, fumes or gases. • Always operate the inverter in accordance with the instructions in this manu

(500W divided by 10V = 50A). 3. Conclusion: The reserve power of the battery is sufficient to satisfy the continuous load demand placed on the inverter for a maximum of about one hour. (49.8 Ah divided by 50A = 1 hour). Note: • When the inverter will be operating equipment or appliances with high continuous load ratings for extended periods, it is not advisable to power the inverter with the same battery used to power your vehicle. If the car or truck battery is utilized for an extended period,

Keep the unit and all cords clear of the steering wheel, gas, brake and clutch To maintain your inverter in proper working condition, note the following important safety precautions: • MOISTURE. Keep the inverter dry. Do not expose it to moisture. Do not operate the inverter if you, the inverter, the device being operated or any other surfaces that may come in contact with any power sources are wet. Water and many other liquids can conduct electricity which may lead to serious injury or death. •

Important Information on Battery Chargers Using your inverter with battery chargers for power tools, flashlights, video cameras and laptop computers may cause damage to the inverter or the charging unit. Check with the appliance manufacturer for compatibility with modified sine wave inverters if you’re unsure. Although we advise against it, if you attempt to use a charging unit, monitor the temperature of the charging unit for approximately 10 minutes. If the charging unit becomes unusually warm

This power surge is referred to as the "starting load" or "peak load." (By comparison, as standard light bulbs do not require a large starting load.) Once the equipment or appliance has up, it settles down to a slower pace and requires far less electrical power to operate. This lower power requirement is referred to as the "continuous load." In order to ensure that the capacity of your Whistler inverter is sufficient to meet the required start up load, you must first determine the power consumpt

Check Whistler’s online store for cable availability. Cable options: For model Pro-2500 at 10 foot length, a subsitute for the #0000 gauge can be using 2 sets of #0 gauge wires connected in parallel to the battery. 12 Making the Connection. 1. Make certain that the Power switch is in 2. Connect the cables to the power input at the rear of the inverter and tighten the screws to make a secure connection. (To make these connections, install the wire connectors flush with the metal backing plates an

• While connecting the inverter to the power source, make certain that the inverter is well removed from any potential source of flammable fumes or gases. • In the event a continuous audible alarm or automatic shut off, turn the inverter OFF immediately. Do not restart the inverter until the source of the problem has been identified and corrected. 23 pro1200to3000w.4/30/2010 8:55 AM Page 27 TROUBLESHOOTING TROUBLESHOOTING PROBLEM: TV Interference Overload LED on Problem Solution Electrical inter
